Abstract:The collision of several coherent 800 nm femtosecond filaments is induced experimentally and in the simulations by transmitting a beam through a mask with 4-6 circular apertures and subsequent focusing with a lens. We show a factor of 1.4 increase in the peak intensity and an order of magnitude increase in the plasma density in the case of 6 filament collision as compared with a single filament. Enhanced energy deposition into the medium attained in this regularized structure is important for rainmaking and acoustic waveguide formation.
